xml - JAXB处理SOAP消息时如何拦截XML解析错误？

Question

我可以使用 JAXB 拦截 XML 解析来检查负载吗？

我已经使用 java 的 wsimport 工具为 SharePoint WSDL 生成了代码绑定(bind)。我在 SharePoint 中调用一个名为 GetListItems 的 SOAP 方法，生成的代码正在为我解析从服务器返回的 XML。

解析失败；这是一个known issue in SharePoint用户可能会在某些破坏 SharePoint 生成的 XML 的内容中放置特殊字符。

这个堆栈跟踪给出了提示 Character reference "&#])(注意那里没有结束双引号)——我现在最好的猜测是有一个不可打印的字符或一些奇​​怪的东西破坏解析的 XML。修复它首先要更多地了解它是如何发生的。有什么建议吗？

您可以在您的客户端中打开 SOAP 消息的日志记录。参见实例 Tracing XML request/responses with JAX-WS 登录到控制台。
